Double Action Belt Cleaner

A new double action device was developed to
improve the belt cleaning operation.
The device is installed under a head drum and
consists of an axle and six rectangular rubber
plates. The axle is supported by two
bearings and is rotated by a chain drive
connected the head drum shaft and the axle.
The rubber plates are mounted on the axle
and have a long steel tips on their free side.
The distance between the conveyor belt and
the axle should be smaller than the width of
the rubber plate.
The rotation of the shaft causes the rotation
of the axle in the opposite direction. Each
plate,firstly, impacts the conveyor belt
and, secondly, scretches the belt some time,
and the next plate is coming , and so on.
The device is a very simple, reliable and....
..good cleaning !

new belt cleaner with steel-tipped rubber blades

I would be interested to receive details about this development.
we manufacture conveyors for handling dewatered wastewater sludge which is usually quite sticky. Has there been any experience with such applications?

Double Action Belt Cleaner

The device is very simple one and was
described in detailes in two my threads.
You can order a set of shop dwgs or
the cleaner ready to use.
If you decide to order, send your belt width,
location of the head drum and chute.

Double Action Belt Cleaner

Tne principle of the device differs from known
cleaners:
the device is installed between head and bend drums
and rotated by a head drum shaft
via a chain. 6 to9 rubber steel-tipped blades are mounted
on the axle. the width of the blades equals to the
width of the belt.
The axle is installed in such way that the blades are
bended to pass the belt.
So, rotation of the head drum causes rotation of the
cleaner in the opposite direction and each blade
firstly impacts and, secondly,screthes the belt,
throwing the material in the low section of the head
drum chute (selfcleaning).
I hope that now operation of the cleaner is clear.

As Mr. Nordell has suggested, the use of rotary rubber blade and rubber brush cleaners have not proven to be successful in the industry. Although they tend to be very efficient initially, as the rubber wears contact with the belt is lost. Unless the operator has an efficient maintenance team the units do not get adjusted and carryover results.

Do the blade arms in your unit have sufficient length to provide for tip wear without having to replace blades monthly or weekly, or does the assembly come with an adjustment which permits operators to move the unit closer to the discharge pulley as blade wear occurs? If the latter, do you handle changes in the chain tension with a dancer sprocket?
